: It used to supply enough hot water for at least three people to shower. Just recently it started running out of hot water before one person had showered.

: It has two heating elements so I am guessing that one of them has gone bad.

: Question 1: The heater was installed less than a year ago by the previous owner. So I don't don't have a reciept and don't know where it was purchased. Is there any possibility I might still be able to get this covered under warranty ?

: Question 2: What do you think is wrong ?

: Question 3: I am willing to tackle this project on my own but have never taken a water heater apart before. Are there any good instructions on the web somewhere ?
